{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Use "Starting year" to ignore publications out of year range.

Determination of plutonium in environmental samples by controlled valence in anion exchange

Chen, Q.J.; Aarkrog, A.; Nielsen, S.P.; Dahlgaard, H.; Nies, H.; Yu Yixuan; et al. (1 more)

Journal of Radioanalytical and Nuclear Chemistry — 1993, Volume 172, Issue 2, pp. 281-288

is heated at 400-degrees-C and digested in aqua regia. Na2SO3 and NaNO2 have been applied to obtain the Pu4+ valence state in 0.571 N HN03 for different samples. Plutonium and thorium are coadsorbed on anionic resin from 8N HN03. The column is eluted with 8N HN03 containing fresh NaNO2 to keep the Pu4

at 400°C and digested in aqua regia. Na2SO3 and NaNO2 have been applied to obtain Pu+4 valence in 0.5-1 N HNO3 for different samples. Plutonium and thorium are coabsorbed on anionic resin from 8 N HNO3. The column is eluated with 8 N HNO3 containing fresh NaNO2 to keep Pu+4 valence for uranium
